Frequently asked questions
What does an S/4HANA migration cost a mid-market company?
Mid-market budgets typically run from a few hundred thousand into the low millions. The license and platform are the visible part. The swing factor is data condition and custom code, which is why two companies of the same size can land a million dollars apart.
What are the three migration paths and how do they compare on cost?
Brownfield conversion is the cheapest, low six to low seven figures over 9 to 18 months. Greenfield reimplementation runs seven to eight figures over 18 to 36 months. RISE with SAP shifts you to a managed-cloud subscription plus migration services. The right one depends on how much of your current process and data is worth keeping.
Why do migration budgets blow up?
Because the data problems are found late. Across the market, 65 percent of programs miss quality targets, 60 percent run an average of 30 percent longer than planned, and 55 percent exceed budget. The slip is in data and testing, not the cutover.
How much of the budget is data work?
Plan 25 to 30 percent of total effort for data preparation and validation, and expect discovery and cleansing to consume about 40 percent of the calendar. Pre-move cleansing cuts post-migration defects by roughly 60 percent, so it pays for itself.
Are consulting rates rising?
Yes. Specialist S/4HANA rates are up 30 to 50 percent through 2026 and 2027 as demand runs near three times supply. The SAP consulting market passed 16 billion dollars in 2025. Waiting raises the rate you pay.
How do we keep the budget realistic?
Start with a readiness assessment so the number rests on evidence, front-load the data remediation where fixes are cheap, choose the path from the assessment rather than a slide, and carry a real contingency for the 30 percent of projects that slip.
What is the most expensive mistake?
Committing to a date and budget before measuring the data. Rework discovered at cutover is the single most expensive line item in any migration.
